<p>A primary hydraulic circuit of a membrane pump consists of a tank (1), suction filter (2), gear hydroelectric generator (3), directly-operated pressure valve (4), dipole four-way electromagnetic distributor (5), primary hydraulic chamber (6), membrane (7), input line (9), leakage line (10), return wire (11) and outlet lines (12, 13). A pulsing pressure of hydraulic oil is obtained by coupling said input line (9) with a first output line (12) and second output line (13) by means of the dipole four-way electromagnetic distributor (5).</p> |
